Perez will go to €11 million-a-year for the former Chelsea manager, with another €1.5 million bonus for each trophy won. Mourinho will also insist on his backroom staff to join him at Real at €1 million-a-year each.

To pay-out Real coach Manuel Pellegrini's contract, it will cost the club €14.5 million.
